Abstract
The utility model relates to a 10kV trolley switch loop resistance testing tool, consisting of a butt contact, a trolley switch contact and tying springs. The testing tool is characterized in that the size of the butt contact is matched with that of the center of the trolley switch contact, the butt contact is cylindrical and is inserted in the center of the trolley switch contact, the tying springs are wound on outer rings of the trolley switch contact, and a contact clamp of a loop resistance tester is connected with the butt contact. The 10kV trolley switch loop resistance testing tool can reduce potential safety hazards of a trolley switch loop resistance test to zero in Class C overhaul work of a 10kV trolley switch, ensures safety production, can ensure the tying springs of equipment from being burnt out, test work can be performed scientifically and reasonably, and operation becomes relatively standard.
Description
Technical field
The utility model relates to a kind of 10kV car switch loop resistance testing tool, is applied to the detection of electric power facility.
Background technology
At present, in 66kV transformer station in the compass of competency of Changchun Power Supply Company's substation equipment maintenance and repair work area, 10kV switch cubicle equipment is more, the annual spring, autumn inspection work is also comparatively heavy, when 10kV car switch C class maintenance in the past, loop resistance for switch is tested, use circuit resistance tester, its contact is clipped on the contact binding spring of car switch, when adding measuring current, because measuring current is larger, easily burn the binding spring, cause power transmission in time, stability influence to equipment is larger, so according to company's " safety first, put prevention first " work safety policies, determine development 10kV car switch loop resistance test specific purpose tool.
Summary of the invention
The purpose of this utility model is to provide a kind of 10kV car switch loop resistance testing tool, it can will be down to zero to the potential safety hazard of car switch loop resistance test in 10kV car switch C class upkeep operation, guarantee safety in production, the binding spring that can guarantee equipment is not burnt, scientific and rationally carry out test job, make to operate standard more.
The technical solution of the utility model is achieved in that 10kV car switch loop resistance testing tool, by butt contact, car switch contact, binding spring, formed, it is characterized in that: butt contact size and car switch contact center size are complementary, butt contact is column type, its front end is less than rear end diameter, on butt contact front end insert head car switch contact center, the binding spring is wrapped in car switch contact outer ring, and the contact folder of circuit resistance tester is connected with butt contact.
Good effect of the present utility model is that it can will be down to zero to the potential safety hazard of car switch loop resistance test in 10kV car switch C class upkeep operation, guarantee safety in production, the binding spring that can guarantee equipment is not burnt, and scientific and rationally carries out test job, makes to operate standard more.
The accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Fig. 2 is butt contact structural drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further: as shown in Figure 1, 2,10kV car switch loop resistance testing tool, by butt contact 1, car switch contact 2, binding spring 3, formed, it is characterized in that: butt contact 1 size and car switch contact 2 center sizes are complementary, butt contact 1 is column type, its front end is less than rear end diameter, in the front end insert head car switch contact 2 of butt contact 1 in the heart, binding spring 3 is wrapped in car switch contact 2 outer rings, and the contact folder of circuit resistance tester is connected with butt contact 1.
During resistance test, first butt contact 1 is inserted on the car switch contact 2 that needs to measure, the contact of circuit resistance tester is clipped on contact head 1, the contact of circuit resistance tester folder does not contact with binding spring 3, the possibility of having avoided binding spring 3 to burn.
